I am wanting to export m my data to a csv file and can't find the file tab.

Hi there Drubine

Those instructions will work in the full 1Password desktop app for Mac, Windows, or Linux. You can download and install 1Password for Mac from here:

☞ 1Password - Downloads - Mac

Then, when you've signed in to your 1Password account, you'll find the File menu in the top-left corner of the screen, near the Apple menu.

I hope that answers your question fully, but please do let me know if I can be of any further help. :)
